Abstract:
AbstractThe male genital tract of Chaoboridae, represented by Eucorethra underwoodi Underwood, Mochlonyx velutinus (Ruthe), and Chaoborus trivittatus (Loew), is described for the first time. All genera have paired accessory glands that are attached anteriorly to the vasa deferentia or the base of the testes, a feature that is proposed as a synapomorphy of Chaoboridae + Culicidae. Mochlonyx Loew and Chaoborus Lichenstein have distinctive pigment cells covering their testes and a portion of the vasa deferentia. The simplified male genital tract of Corethrellidae + Chaoboridae + Culicidae is correlated with the virtually unique abrupt and permanent 180° rotation of the male genitalia between segments 7 and 8. In taxa with an accessory-gland complex, the male genitalia are rotated in a more gradual manner, often during copulation.

Abstract:
AbstractA new species, Chaoborus sampsera, is described from male and female adults collected from Papua Province in western New Guinea, Indonesia. Based on leg banding, wing pigmentation, and possession of a median paramere sclerite in males, the new species belongs to the Chaoborus “pallidus” group of Colless. Chaoborus sampsera is distinguished from other species of the “pallidus” group by the scimitar-shaped parameres. Although relationships among these Chaoborus species are unclear, there are morphological characters that support the “pallidus” group.

Abstract:
Foram avaliados os efeitos da estrutura física de habitats em comunidades de macroinvertebrados bentônicos em três reservatórios: Serra Azul (SA), Vargem das Flores (FV) e Ibirité (IB). Mensurações de variáveis físicas e químicas e comunidade bentônica foram realizadas em 30 estações de amostragem em cada reservatório. Em SA, foram coletados 12 táxons com predomínio de Melanoides tuberculatus Müller, 1774 (15,2%) e Chaoboridae (63,8%). Em VF foram coletados 11 táxons sendo M. tuberculatus (34,2%) e Oligochaeta (33,6%) os dominantes. Em IB foram coletados 7 táxons com domínio de M. tuberculatus (91,2%) e Chaoboridae (6,27%). Em Serra Azul foi observada influência significativa do sub-bosque arbustivo e do ângulo de inclinação do barranco. Nos reservatórios de Ibirité e Vargem das Flores as variáveis significativas foram cobertura do solo, influência humana e macrófitas aquáticas. Concluímos que as ações humanas reduzem a cobertura da vegetação terrestre e a complexidade de habitats físicos na região litorâneos dos reservatórios, levando a uma redução na qualidade de água. Essas mudanças, por sua vez, reduzem a riqueza taxonômica dos macroinvertebrados bentônicos.

Abstract:
Abstract Understandings of natural enemy efficacy are reliant on robust quantifications of interaction strengths under context-dependencies. For medically important mosquitoes, rapid growth during aquatic larval stages could impede natural enemy impacts through size refuge effects. The identification of biocontrol agents which are unimpeded by ontogenic size variability of prey is therefore vital. We use functional response and prey preference experiments to examine the interaction strengths and selectivity traits of larvae of the cohabiting predatory midge Chaoborus flavicans (Meigen 1830) (Diptera: Chaoboridae) towards larval stages of the Culex pipiens (Diptera: Culicidae) mosquito complex. Moreover, we examine the influence of search area variation on selectivity traits, given its importance in consumer-resource interactions. Chaoborids were able to capture and consume mosquito prey across their larval ontogeny. When prey types were available individually, a destabilizing Type II functional response was exhibited towards late instar mosquito prey, whereas a more stabilizing Type III functional response was displayed towards early instars. Accordingly, search efficiencies were lowest towards early instar prey, whereas, conversely, maximum feeding rates were highest towards this smaller prey type. However, when the prey types were present simultaneously, C. flavicans exhibited a significant positive preference for late instar prey, irrespective of water volume. Our results identify larval chaoborids as efficacious natural enemies of mosquito prey, with which they frequently coexist in aquatic environments. In particular, an ability to prey on mosquitoes across their larval stages, coupled with a preference for late instar prey, could enable high population-level offtake rates and negate compensatory reductions in intraspecific competition through size refuge.

Abstract:
This study documents dynamic changes in the mean abundance and body size of arthropods in an ephemeral pond over the course of a summer in order to understand the nature of interactions that shape this community, and to assess the risks posed by exposure to cercariae of the entomopathogenic digenean, Plagiorchis elegans, a potential control agent for larval mosquitoes. Chironomids were the most abundant, comprising almost two-thirds of all arthropods collected; they were followed by chaoborids, the most abundant predator. Other arthropods, in decreasing order of abundance, were the ephemerids, isopods, amphipods, odonates, dytiscids, and hemipterans. Infections were found only in chironomids and were extremely rare and of low intensity, conceivably due to predation of chaoborids on cercariae and may have protected the community from exposure to these parasites. Findings are discussed in terms of using entomopathogenic digeneans as agents in the biological control of mosquitoes.

Abstract:
Bien que fonctionnant en sous-charge, la lagune de traitement des eaux usees de la salvetat-peyrales est un milieu hypereutrophe. En effet, les teneurs en composes azotes et phosphores sont tres importantes et permettent, associees a un regime thermique eleve, le developpement de forts peuplements phyto- et zooplanctoniques. Ce dernier est domine par les populations de rotiferes - notamment brachionus calyciflorus - et celle de daphnia pulex. Une population monospecifique de chaoborus flavicans trouve dans ce milieu d'excellentes conditions qui lui permettent de realiser cinq generations par an et d'atteindre, en octobre, une abondance maximale de 21 586 larves/m#2. La biomasse (2,532 g poids sec/m#2), la production (352,5 kg poids sec/ha/an) et le rapport p/b (14,5) associes a cette population sont nettement superieurs a ceux rapportes par des travaux anterieurs. Les comportements d'enfouissement dans les sediments et de migration verticale des larves de stade iv et des nymphes sont comparables a ceux decrits dans des milieux plus profonds ; ils semblent etre regules par les variations de l'intensite lumineuse. Le regime alimentaire des trois premiers stades larvaires est essentiellement compose par le rotifere b. Calyciflorus. Celui du stade iv est plus large, mais reste base sur les deux proies preferentiellement selectionnees, b. Calyciflorus (% i. R. I. = 60,7%) et d. Pulex (% i. R. I. = 31,0%). La biomasse zooplanctonique quotidiennement eliminee par les larves de c. Flavicans a ete estimee a 11%. En milieu controle, la plupart des pontes deposees sont steriles. Plus les conditions de vie des adultes de c. Flavicans sont proches de celles observees dans le milieu naturel, plus le taux de fertilite des ufs augmente. Le comportement sexuel des imagos (formation d'essaims, accouplements) semble etre independant de la presence/absence de plantes littorales, mais parait etre sous l'influence directe des variations de l'intensite lumineuse liees au crepuscule et a l'aube. Lors de l'optimisation du developpement larvaire de c. Flavicans en laboratoire, la temperature de 25c a ete retenue comme etant celle offrant le meilleur compromis - au stade iv - entre la duree de la phase larvaire (17,3 2,4 jours), le taux de survie (52,3 18,7%) et le poids individuel (3,064 1,138 mg). A cette temperature, le taux de nutrition moyen est respectivement, du stade i au stade iv, de 37,3, 22,4, 10,9 et 5,0% du poids larvaire. Enfin, les collectes realisees en milieux naturels (lagunes, lacs collinaires) sont tres irregulieres et dependent de nombreux facteurs (niveau trophique, techniques de collectes, vent, phase lunaire, etc. ) qui les rendent aleatoires

Abstract:
Lake sediments contain the remains of midge communities that may be used as biological proxies for inferring past environmental changes. Freshwater midges, including Chironomidae and Chaoboridae, from two alpine tarns (Pyramid Lake and Bullwinkle Lake) in the Cassiar Mountains of northern British Columbia were used to estimate Holocene palaeotemperature changes, and more specifically, to test for the presence of the Milankovitch thermal maximum, an early Holocene warm interval coinciding with peak Holocene summer solar insolation. Mean July air temperatures were reconstructed using midge-inference models developed via weighted averaging-partial least squares (WA-PLS) regression. Cold-tolerant midge taxa dominate the stratigraphies from both Pyramid and Bullwinkle Lakes; however, warm-adapted species are more common in Bullwinkle Lake. Early Holocene warming is apparent at both lakes, however it is unclear whether this is indicative of the Milankovitch thermal maximum. A decrease in temperature occurs from 8,700-7,900 cal. yr BP at Pyramid Lake, around the same time that the 8,200 cal. yr BP cooling event occurred in the northern hemisphere. During the middle Holocene, records from Pyramid Lake indicate an overall decrease in temperature, with a short period of warmer temperatures that peak at 5,100 cal. yr BP. Temperatures fluctuate little during this time at Bullwinkle Lake. A short warming phase is apparent at both lakes during the late Holocene. July temperatures are highest at 2,000 cal. yr BP (10.5°C) in Pyramid Lake and at 1,200 cal. yr BP (13°C) in Bullwinkle Lake. Thereafter, temperatures return to what they were before the warming occurred, and at Bullwinkle Lake, vary little throughout the remainder of the Holocene.
